$0  That's a zero.  Has always worked for me to produce a full  
path to a running perl script.

...There is a module "cwd"...

or rather Cwd.  $0 will give the name but not the full path, so I'd  
suggest
the following:

#usr/bin/perl
use Cwd;
my $currentdir = cwd();
print "$currentdir/$0\n";

That's for a relative path.  It would fail if $0 is an absolute path  
to begin with, the cases would have to be distinguished.  To be truly  
portable, it should also make no assumptions about the directory  
separator.  That's what Dir::Self (available on
CPAN) does.
